Notes:
1. Device tested and characterized under T
A
conditions specified, with T
C
monitored at approximately 20
°
higher than T
A
.
2. This is the recovery time for input phase jumps, per the FC-PH specification Ref 4.1, Sec 5.3.
3. Tested using C
PLL
= 0.1

4. The RBC clock skew is calculated as t
A-B(max)
- t
A-B(min)
.
5. The receiver latency, as shown in Figure 6, is defined as the time between receiving the first serial bit of a parallel data word (as
defined as the first edge of the first serial) and the clocking out of that parallel word (defined by the rising edge of the receive byte
clock, either RBC1 or RBC0).
